My Mermaid Bodyguard Stole My Heart
A brave mermaid princess leaves the ocean and lands a job as a bodyguard for a tormented wealthy heir. Paralyzed from a poacher‑orchestrated accident, the man sets a 90‑day euthanasia schedule, having lost all desire to keep living. The mermaid constantly intervenes in his closed‑off life and slowly reawakens his will to survive, and genuine love grows between them. His greedy former fiancée and her accomplice chase the mermaid, hoping to capture her and cash in on her special aquatic abilities. She risks herself and sacrifices her native mermaid magic to save the heir. After experiencing kidnapping, deadly laboratory fights and risky underwater adventures, the heir gives up his human identity and turns into a merman. They defeat the vicious conspirators, ease conflicts between humans and undersea inhabitants, and finally achieve sincere mutual redemption.
Story Guide
Episode 1
A good deed turns into a job interview. Marina Calloway saves a stranger's life in a chaotic moment, then rushes off because she's late for an interview. The woman waiting for her is Decklan Wade, who isn't hiring just any guard—she wants a bodyguard for her son, Decklan Wade.
Then comes the gut punch. Decklan Wade says her son has 90 days left, and that he signed papers with the hospital for euthanasia three months from now. She's desperate. If this girl can fight the ocean, maybe she can fight him. Marina takes the job without knowing what she's walking into.

Episode 2
The interview gets physical: guns, fighting, driving, strength. Marina proves herself by hoisting a grown man off his feet, and just like that, she's in—with a 500k signing bonus. Her first priority is simple: make sure Decklan takes his medication on time.
Decklan, though, has other plans. He tells her to get out and offers to double whatever his mother is paying her. Marina's answer is a threat wrapped in a smile—take the medicine, or she'll give him a bath. He tries to spit it out. She doesn't let him. "Good boy," she says. He warns her never to feed him like that again.

Episode 3
Decklan needles her about not liking to be touched—while his own hand is still on her. Marina fires back about his temper and tells him he needs sun. What follows is a chaotic forced outing: a reckless ride that turns into a near-disaster, with Marina steering and Decklan shouting for her to stop.
When it's over, he's wide awake and rattled. He demands to know what she is, because something about her doesn't add up. Marina deflects, but the question hangs there. He's starting to suspect his new bodyguard is far more than she appears.
Episode 4
Marina drags Decklan outside and announces sunlight and photosynthesis—you're welcome. Decklan Wade is stunned to see her son out of his room, in one piece. But Decklan is furious, ordering security to throw Marina out. His mother sees something else: he's finally angry, finally using his voice.
So she makes it official. Marina is hired, day and night, to keep him alive. Decklan flatly declares his euthanasia is booked in exactly three months and nothing will change that. Marina promises to look after him for the rest of his life. The standoff is set.
Episode 5
Marina brings Decklan a strange gift—a crab that moves to cheer him up. He refuses to let it near his food, but the small absurdity cracks his walls. Decklan Wade admits that since the accident, Decklan has shut down completely: no physical therapy, no doctors. She wants Marina on him constantly.
Marina promises to guard him fiercely—anyone who touches him answers to her. Decklan Wade offers double the bonus if she can change his mind. But there's a catch: Decklan skipped his morning dose, and that's a penalty against Marina's payout. When he refuses again, she asks if he wants a repeat of last time.
Episode 6
Decklan heads upstairs for a shower—alone, he insists. Marina is ready for the next battle: pill time. He tells her to get out, and she doesn't blink. If he won't drink it, she'll give him a bath. Choose one.
He accuses her of doing all this for cash. She owns it—up here, even a decent glass of water costs a fortune, and she knows water like the back of her hand. He accuses her of enjoying watching a Wade squirm. Maybe, she says. Then the moment turns: he's still holding on to her, and she reminds him this is purely professional. But the look between them says otherwise.
